Electrical power for controlling the ignition system etc is not turning off and if it is not the ignition switch, it could be a faulty relay or something is shorted to power.

Ok what relays could be corisponding with those componets and no new exeseries all my money just went in to switching out the fuel gadeg and sending unit and the ignition switch and the tumblersystem. Any tips on trying too pin point a ground power wire. That is the case. Or any images that might help me see what circut lay out for it is. Thank you for every thing.

SEE DIS?

I HAVE REALLY BEEN THINKING HARD. AND DID COME UP WITH A POSSIBILITY!

QUITE A FEW HOURS OF "PIDDLING" ON THE COMPUTER AND A LITTLE LEG WORK

THIS IS FOR A '79 CJ---I SCANNED A TEENY TINY DIAGRAM---COLORED THE WIRES----IF YOU HAVE A PRESTOLITE IGNITION (THIS DIAGRAM IS "MOTORCRAFT IGNITION"----THE MODULE AND DISTRIBUTOR WIRING ARE SLIGHTLY DIFFERENTAS FOR IGNITION SWITCH AND COIL THEY MAY BE CLOSE TO/ OR THE SAME

I BELIEVE YOU HAVE AN ISSUE WITH SOMETHING CROSSED UP AT THE SOLENOID/ COIL/ ON THE WAY TO THE SWITCH

SOMETHING IS MAKING YOUR COIL HOT CONSTANTLY

MY SUSPICIONS NOW ARE THE "I" TERMINAL ON THE SOLENOID IS "HOT" CONSTANTLY DUE TO AN INTERNAL FAILURE IN THE SOLENOID (SHOULD GO DEAD WHEN "S" IS NO LONGER ENERGIZED). REPLACE IF THIS IS THE CASE

TO VERIFY MY SUSPICION----DISCONNECT "I", AT THE SOLENOID. JUST AS A TEST. THE JEEP WILL PROBABLY STILL CRANK UP AND RUN (MINE WILL). AND TURN OFF WITH THE KEY. THEN REPLACE THE SOLENOID!

OR YOU HAVE HOOKED SOMETHING UP WRONG!

I BLEW UP AND CONNECTED THE 2 DIAGRAMS--THEN LAMINATED IT

I'M SENDING 3 PICS---LET ME KNOW IF YOU WANT THE ENTIRE COLORED DIAGRAM (2 PIECES).I WILL INITIATE A WAY FOR YOU TO COVERTLY SEND YOUR EMAIL ADDRESS

IF YOU DID DO SOMETHING STUPID---PLEASE GIVE IT UP---OTHERS READING THIS WILL BENEFIT!

YOUR TURN
